The Solution to a faster SSD while using Windows is to disable the D2D Recovery function in BIOS.
For some people it helps instantly, but i had to put Windows on again to get the effect.
So you should disable it BEFORE installing Windows.
I made a Ghost image of my XP install, disabled D2D and deployed the Image back on the Aspire One.
After that the SSD reacts a lot faster, like under Linpus. So no need for special Drivers.
Using FAT32 helps too. The file System ist much simpler what results in less writing operations which are slow on the low cost SSD.
If you upgrade your RAM as i did (1,5 GB) you should also consider disabling the Pagefile and maybe putting the cache directories
on a SD Card to avoid to much writing operations.
I put that all in my Wiki (its German):

You can find a HOWTO on upgrading your RAM. But because acer says that it will void your warranty make sure what you do.
You can find the Drivers for Windows there too, getting all devices to work under Windows.
I took me some research on the net, the drivers are not official by Acer but working well.
